Abstract (en)

[origin: EP3663675A1] Provided is an air-conditioning system (100), comprising a refrigerant compressor (411), a high-pressure gas refrigerant pipe (430), a low-pressure gas refrigerant pipe (440), and a plurality of air-conditioners (300). Each air-conditioner has a first heat exchanger (341); a second heat exchanger (342, 343); a housing (301); and a pipe connecting mechanism (370). The pipe connecting mechanism is configured to connect each of the first heat exchanger and the second heat exchanger to a refrigerant compressor (411), via the high-pressure gas refrigerant pipe and the low-pressure gas refrigerant pipe (440), such that the first heat exchanger, the second heat exchanger and the refrigerant compressor form a heat pump circuit, and includes a switching mechanism configured to switch the state of the air-conditioner between a cooling mode connection state and a heating mode connection state.
